Derivatives of Hyperbolic Functions. For all real numbers x, we have: (a) d dx (sinhx) = coshx. (b) d dx (coshx) = sinhx. (c) d dx (tanhx) = sech2x. If you prefer to stay away from the hyperbolic secant function sech x, you can write the third derivative above as. 1 cosh2 x . Proof. The proofs of these differentiation formulas follow
Derivatives of Hyperbolic Functions. The last set of functions that we're going to be looking in this chapter at are the hyperbolic functions. In many physical situations combinations of and arise fairly often. Because of this these combinations are given names. There are the six hyperbolic functions and they are defined as

Let y="f"(x) be a function of x. Its derivative w.r.t. 'x' is denoted by dy/dx or y1 or f'(x). This is called first derivative of y w.r.t.x.. The derivative of first derivative of y is called second derivative of y and is denoted by d 2y/dx2 or y2 or f'(x). The derivative of second derivative of y is called third derivative of y and is denoted by d3y/dx3
Proof of (d/dx) csch(x)= -coth(x)csch(x), (d/dx) sech(x) = -tanh(x)sech(x), (d/dx) coth(x) = 1 - coth2(x) : From the derivatives of their reciprocal functions. Given: (d/dx) sinh(x) = cosh(x); (d/dx) cosh(x) = sinh(x); (d/dx) tanh(x) = 1 - tanh(x); csch(x) = 1/sinh(x); sech(x) = 1/cosh(x); coth(x) = 1/tanh(x); Quotient Rule. (d/dx) csch(x)=
